Suppose I had measured the lifetimes of a random sample of 100 tires rather than 64. Which statement is TRUE? The margin of error for our 99% confidence interval would increase. The margin of error for our 99% confidence interval would decrease. The margin of error for our 99% confidence interval would stay the same since the level of confidence has not changed. σ would decrease.

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.

What is the distance from zero if a quadratic function has a line of symmetry at x=-3 and a zero at 4
